National Council on Economic Education (NCEE) maintains an online economics literacy test . Among the key findings of the online test:

"Half of all American adults receive a failing grade for their knowledge of basic economic concepts. Adults who have completed college score dramatically higher than those who have not.

- On average, American adults get a grade of 57% for their knowledge of basic economic concepts.
- Only six percent of adults receive a grade of A, and ten percent receive a grade of B.
- Three out of five (60%) college-educated Americans score C or better while only three in ten (32%) adults with some college and fewer than two in ten (17%) adults with a high school education or less do the same.
- Working Americans score higher than non-working Americans. Just over one in three (36%) working Americans compared to one in five (20%) non-working Americans receive a grade of C or better.
- Men (40%) are more likely than women (22%) and white adults (36%) are more likely than black (13%) and Hispanic (9%) adults to receive a grade of C or better for their understanding of economic concepts."

I got 20 out of 20 questions correct. Not bad.
